Certclad Weatherboards CertClad is the ITI Timspec brand name representing certified cavity-based weatherboard cladding system. It has been tested and assessed in accordance with the requirements of NZ Building Code clause E2/AS1 by a third-party organisation and has attained CodeMark certification.
What is CodeMark?
CodeMark is a voluntary product certification scheme that provides an easily understood and robust way to show a building product meets the requirements of the New Zealand Building Code. A product can be a building, construction method, building design or a building material. CertClad systems are CodeMark certified and are approved to be used as a partial or full cladding system for residential or small scale commercial building types.
Testing, Compliance & Consenting
The CertClad weatherboard systems are audited annually by a third party independent auditor, within the framework of JAS-ANZ. These systems are not only compliant to NZ Building Code but, exceed the minimum requirements. Moreover, CertClad certified systems are deemed to comply, and are generally not subjected to the discretion of consenting authorities in New Zealand.
The warranty for each species and or system is outlined in the relevant CertClad system documents. CertClad cladding systems are warranted only if, installed using ITI Timspec approved products and in accordance with the installation manuals and drawings provided by ITI Timspec. For more information please call us on (09) 620 0260.
How it helps your building consent process
Easier - Less hassle and easier for both the applicant and the Territorial Authority.
Quicker- The Territorial Authority does not need to do any background research, they simply need to check the validity of the CodeMark certification.
Guaranteed to be Accepted- Legislation states that a Territorial Authority must accept CodeMark certified products as complying with Building Code. As long as your building is within the scope and follows the installation specification it will be accepted. No more annoying rejections and having to re-submit your application.
Certainty - You get peace-of-mind knowing that the system has undergone testing, investigations, and audits to prove that it will stand the test of time.

ITI Timspec is subject to annual audits and has strict Quality Assurance Systems in place to ensure that everything we do is up to standard.
